Swarm and Fuzzy

Stigmergy gets a bit of a mention in Newsweek.

Swarms often work by “stigmergy,” a term coined by French biologist Pierre-Paul Grassé in 1959 to describe termite behavior. He defined it as “the stimulation of workers by the performance they have achieved.” It has come to mean a mark left in the environment. Think of stigmergic marks as road signs: A termite makes a ball of mud laced with pheromones (chemicals that affect behavior through smell) and puts it down. The next mud-ball-making termite that happens along smells the first, makes its own ball and adds it to the pile. Millions of balls later, a hollow mud spire stands 8 feet tall, as outlandish as the towers of Turkey’s Cappadocia region—a magnificent termite-apartment complex.

Each individual in a swarm acts seemingly at random—scientists term this “stochastic”—yet as a group a swarm is amazingly focused, coherent and logical.

Translating nature to math can be staggeringly difficult.

David Chalmers and Andy Clark Interview

This from the New Philosopher.

Andy’s colleagues at Edinburgh in the epistemology department proposed the extended knowledge project, where you start thinking of knowledge as this extended process that involves interaction with the environment.

I’ve been calling it stigmergic epistemology.

Systems and Complexity Thinking in the General Practice Literature: An Integrative, Historical Narrative Review

Here’s an interesting survey article. My regular collaborator (a pathologist, special adivisor for planning for a large medical school and a complexity theorist — all one person I might add) has been subtly implementing such an approach for many years. What is unusual (and I think right) about the graphic below is that though all of the giants of the complexity are there, Varela and Maturana are not typically viewed in such company. Nice touch.
